I've had the truck just one week and really like it. Previous Ford trucks include a 1949, 1973 cab over with 292 Cummins, and 2000 F350 6.8. Only other diesel was a 2010 GMC 3500. Also an excellent truck except for throwing bogus codes for contaminated DEF and low DEF.

I have an appt next week for oil and filter change. Because I don't know the truck's recent history I'll change both fuel filters. Considering draining coolant, tranny, and transfer case. Sound ok? Suggestions,
Thanks
